Airbus Military's ability to meet the contracted schedule milestones continues to be the greatest challenge. Delays experienced with aircraft development have impacted the associated design, development and verification of the Support System. There is a moderate level of technical and schedule risk associated with certification and qualification testing of the new military avionics and refuelling systems. Risks with development of the boom system have been mitigated through completion of testing on the Airbus Military A310 Boom Demonstrator test bed. Risks with development of the military avionics are being managed through comprehensive subsystem and system-level bench testing.
